You know that you need to change your warm air furnace filter in order to keep your furnace running effectively and to improve your home’s air quality. But how do you know when to change it?

The first place to look is at the owner’s manual that came with your furnace. How often to change your filter will also depend on the type of filter you have, if you have pets and whether someone in the home has allergies. That being said, disposable filters that are fiberglass or electrostatic should typically be changed about once a month to once every three months. Pleated filters should usually be changed once every three months up to once each year.

If you’re wondering whether to change your furnace filter or not, you’re better off doing it now rather than waiting. If you wait too long, the filter can get clogged, making your furnace work harder and therefore run less efficiently, not to mention shorten the life of your furnace. If you’re not sure what type of filter to buy, look at the owner’s manual that came with your furnace or contact your Minnesota HVAC experts at Stay Comfy, Minnesota.
